Spartan Equipment PAGE 3 Professional Brush Cutters May 2014
Operator Safety Training Tips It is the responsibility of the operator using
this attachment to be acquainted with the
safe operation. In addition to reading this
manual, it is important that the operator
read the skid steer's operation manual and
follow its manufacturer's
recommendations!
Before lifting or lowering the cutter,
make sure the area is clear of
bystanders or objects.
Machinery parts sometimes have sharp
edges. Wear work gloves when moving
parts. Always use caution around cutter
blades as they often are very sharp.
Never use drugs or alcoholic drinks when
operating or servicing this piece of
equipment.
Always wear the proper personal
protection equipment when servicing or
operating this piece of equipment. Never
service or operate this attachment with
bare feet, sandals, or other light footwear.
Always use eye protection during
operation. Mount this attachment on a
skid steer equipped with thermoplastic
polycarbonate door panel and side panels.
Speed Kills! Operate this implement
at a safe working speed. When
transporting the implement, keep a
safe speed to avoid losing control of
the attachment or prime mover.
Keep proper clearance between the
implement and objects (utilities, tree
stumps, large rocks, buildings, etc.).
Contacting these objects with the
implement or prime mover could
cause a loss of control or damage to
the implement or property.
Before each operation of this
implement, check all hardware (bolts,
nuts, pins, etc.) for their proper location
and tightness.
Stop the engine on the skid steer and set
the brake to avoid the implement rolling
forward or backwards while you are exiting
the prime mover.
Store this implement in an area not
frequented by children.
Allow no riders on this attachment.
Keep all bystanders clear of attachment
during operation.
Always replace worn, torn or missing
safety decals before operating.
Never operate the cutter when
bystanders are within 75 feet (23 m) of the
work area.
Cut only during daylight or well-lit
artificial light
Spartan Equipment PAGE 4 Professional Brush Cutters May 2014
Skid Steer Requirements Your Professional Brush Cutter should
only be used on a skid steer with a lift
capacity of at least 1800 Ibs. and with a
weight of at least 6500# with the bucket
removed. A skid steer equipped with
tracks will provide superior stability in this
application.
The availability and capability of a high-
flow system on your skid steer loader
may determine which model
Professional Brush Cutter will work best
for you.
To protect the operator from any flying
debris, it is important that the skid steer
should be equipped with a thermoplastic
polycarbonate windshield or similar
material, and similar protection on the
sides of the operator's cab.
I Make sure your skid steer is in good working condition. Follow the operating instructions found in the manual that accompanied your skid steer. Failure to do so could result in Minor or Serious Injury.
Unpacking Your Shipment Your attachment arrives from the factory
banded to a wooden pallet, and requires
no final assembly before use.
Careless removal of the shipping bands that secure the implement to the pallet could result in Minor or Serious Injury. Clear the area of all bystanders and stand to the side when cutting the bands with a pair of sheet metal shears.
Using Your Implement Connecting Cutter to Skid
Steer
~ DANGER Never enter the area underneath the coupler or any part of the attachment when it is in the raised position to avoid an accident that will result in Death or Serious Injury.
Verify that the hydraulic hoses are clear
from the front of the attaching plate on the
attachment and that the mounting plate is
free from dirt and debris. When clear,
move the skid steer to proximity of
attachment plate. Tilt skid steer coupler
forward to align coupling point with the
upper part on the attachment plate and
raise the coupler slightly.
Connecting Coupler to Attachment
When the top edge of the coupler is
seated in the top part of the coupler plate,
roll the skid steer tilt function back until the
attaching plate is flat against the skid
steer coupler. Lock down the coupler
levers. Note: If your skid steer is equipped
with a hydraulically operated coupler,
activate the coupler lock at this time.
Wipe off any dirt or dust from the male or female hydraulic flat-face couplers with a clean rag before attaching hoses, to keep contaminants from entering the hydraulic system.
Connect the attachment hydraulic hoses
to the auxiliary supply couplers located
on your skid steer loader lift arm.

5. Check the skid steers hydraulic oil
level, and add oil if necessary.
6. Inspect the cutter hydraulic plumbing for
any noticeable leaks. Correct these leaks
before continuing.
7. Restart the skid steer. With the
attachment raised off the ground and the
engine throttle set just above idle, engage
the cutter drive circuit to start cutter. Allow
cutter to come up to speed before
increasing engine speed.
Starting the Cutter
Moving or engaging the cutter with bystanders in the area could result in Death or Serious Injury. Before engaging cutter hydraulics, always make sure the area is clear of bystanders.
Engage the cutter drive hydraulics with the
prime mover's engine at a low rpm. Slowly
raise the skid steer engine's rpm to the
correct and desired cutter speed. Use the
skid steer's hand throttle to set the speed;
never use a foot throttle when using the
cutter.
lf the cutter ever creates a vibration when ramping up speed, turn the cutter attachment to the off position and investigate cause. Refer today Troubleshooting section in this manual.
Stopping the Cutter
When stopping the cutter, raise the
cutter slightly and lower the skid steer's
engine RPMs to an idle, and allow the
cutter to slow down. After the cutter has
slowed down you may turn the auxiliary
hydraulics to the "off" position.
Getting Familiar with the Attachment
@ DANGER Never operate the cutter when bystanders are within 75' (23 m) of your work area. Flying debris could result in Death or Serious Injury.
Be cautious when operating on un-level ground surfaces. A machine roll over could result in Minor or Serious Injury. Always wear your seat belt when operating this type of machinery.
Before starting the skid steer engine with
this cutter attached, make sure you are
knowledgeable and comfortable with the
operation of the brush cutter controls as
outlined in the previous and following
sections of this manual.
Do not over-speed the cutter by allowing more than 20 GPM to the cutter head. This attachment requires 11-20 gallons of flow to cut efficiently.
When operating the cutter, set the skid
steer throttle at a speed that will produce
the required flow. Refer to your skid steer
manual or call your local skid steer dealer
for additional help, if necessary. Your skid
steer dealer can measure the flow
available on your machine and
recommend a throttle setting that is
compatible with this attachment.
To begin with, learn what the cutter head
looks like in a level cutting position when
you are seated in the skid steer. Knowing
what a level cutter head looks like will help
you avoid damage to the cutting blades by
cutting too close to the ground surface.
Spartan Equipment PAGE 7 Professional Brush Cutters May 2014
The correct ground speed for cutting with
this attachment can be monitored by
sound and feel and depends on the
material density. If the skid steer engine
is bogging down or if the cutter speed is
turning too slow because of too much
load, the ground speed should be
decreased.
Listen and feel for any strange vibration
when working the cutter. A bad vibration
felt when cutting could indicate a
damaged cutting blade, or material trying
to be cut at too fast a pace. Slow down
the skid steers ground speed to see if
vibration stops. If it does not, stop the
cutter, turn off the skid steer engine and
investigate cause of vibration. Refer to
the Troubleshooting section in this
manual for further instructions.
Always be aware of your surroundings.
While watching the cutter, also pay
attention to what obstacles or terrain are
in front of the cutter and prime mover's
wheels. Maintain a safe speed while
cutting.
Cutting tree branches with the cutter in an elevated position could result in Death or Serious Injury if the skid steer becomes unstable. Never raise the cutter more a few feet off the ground when working on slopes or uneven terrain.
Adjusting Cutter Height & Level
Use the skid steer loader lift to adjust the
elevation of the cutter. The fore & aft
leveling can be accomplished by using
the skid steer's attachment tilt cylinders.
When cutting dense or heavy material, you may
want to adjust the level of the cutter deck so the front of the cutter is approximately 1" (25mm) lower than the back of the cutter. This will assist the processing of the material and will avoid material "balling" under the deck.
Use care when operating on uneven terrain or any type of sloped surface. Keep your cutter low to the ground when working in these conditions to avoid a roll over that could result in Minor or Serious Injury.
Before Cutting
Inspect the area to be cut and make sure
it is free of any utilities, rocks, fence
posts, or any other objects that you do
not want to cut or that would damage the
cutter.
Determine a safe cutting pattern
before the start of the cut. Stop the
forward progress of the skid steer
loader.
Do not enter into an area to be cut before
the cutter rotation come up to the
operating speed.
Cutting Tips
Never operate this attachment when bystanders are in proximity of the work area that could result in Minor or Serious Injury from flying debris.
1. Always inspect work area before
starting the cutter. Locate and
mark any utilities, steel posts,
rocks or any other objects that
could be damaged or would
damage the cutter during
operation. Never assume the work
area is safe and never skip
Spartan Equipment PAGE 8 Professional Brush Cutters May 2014
8.
the inspection part before start of
operation.
2. Operate at a safe slow-paced speed
that will allow you to watch the area
ahead of the cutter & loader.
3. Make sure you are operating the
skid steer's engine at an rpm that will
produce the volume of oil flow
required for this attachment.
Cutting Ground Level Vegetation
4. Raise the rear of the brush cutter
approximately 4" (102 mm) above
ground level. The deck should be
slightly sloping downward away
from the operator.
~t
5. Your rotary brush cutter is capable
of cutting and mulching small trees
and other vegetation of up to 3"
(76mm) in diameter. Learn and
realize which way the tree is likely
to fall so it does not end up
crashing onto you in the skid steer.
Do not operate the
cutter if you (the operator) can see the
cutter blade. If the operator can see the
cutter blade, the back of the cutter is
raised TOO HIGH and should be
lowered to avoid debris being thrown
back at the operator and causing Minor
or Serious Injury.
Cutting Above Ground Level Vegetation
6. Tilt the front of the deck
approximately 1 to 2 feet above
ground level, but do not raise the
rear of the deck. Drive slowly into the
vegetation and use the hydraulic tilt
to bend or push the vegetation
forward. Allow the cutter blade to cut
the vegetation.
Lower the front of the deck as you
continue to much the material. Back
drag the cutter to further minimize the
size of the debris.
7. If the cutter speed slows down,
reduced your travel speed and
allow cutter to reach the proper
rotating speed. Mowing too fast
in thick material could result in balling
of material underneath the cutter
deck resulting in a loss of cutting
efficiency.
8. Never use your cutter to push, pull,
lift or move any type of object or
vehicle. Do not use this attachment
to "push" down trees without the
cutter being used.
9. Always allow cutter to come up to
operating speed before moving
attachment into the material you
want to cut.
Maintaining your Attachment
Before Every Use Check that all fasteners (nuts, bolts,
pins, keepers) are in their right place
and are tight.
Inspect and replace any worn, torn or
missing safety decals.
Investigate the location of any oil leaks
and repair.
Every Week Check the condition of the blades by
raising the cutter attachment off the
ground and tilt the attachment forward to
the 90° position. Lower the attachment to
the ground.
Inspect the cutter blades and remove
and sharpen them if necessary. Sharp
cutter blades will cut more efficiently
than dull blades.
Spartan Equipment PAGE 9 Professional Brush Cutters May 2014
After Every Season Inspect the implement for any loose or
worn parts that may need to be replaced
prior to the next cutting season.
Visually inspect the cutting blades.
Sharpen or replace them, if necessary.
Clean, sand & repaint any area that
looks worn or scratched to prevent
further rusting. Use an equipmentpaint
found at your local hardware store or
building center.
Store your implement in a shed or
cover with a water-proof tarp to protect
it from the weather. Store in an area not
frequented by children.
